Compare Two Starter TTRPG Systems for a First-Time GM

You have played plenty but never sat in the GM's chair, and the wrong first system can make that chair feel permanent. This compares prep demands, how forgiving each system is of an improvised ruling, ready-made starter adventures, and how steep the learning curve is for your players, not just you.
